what is the score with GDA's?
anyone?
Berberine could be worthwhile. The other ingredients in the typical formulas might not do much.
I saw this GDA a while back which is supposed to sort of work differently than other GDAs by actually increasing insulin, geared towards muscle gain rather than fat loss.
